Adam$$s employer contributed $$20,000$ to his superannuation fund in the $2017/18$

financial year. Adam also made $$4,000$ in personal contributions during the

same year. Adam$$s wife, Mary, does not have very much superannuation

because she has been working on a part$-$time basis since the birth of their son.

Adam talks to his superannuation fund about splitting his $2017/18$ contributions

jointly with Mary. He completes the application for superannuation

contributions splitting, indicating he wishes to split $$20,000$ to Mary, and lodges

the application with his fund in August $2018.$

Describe any potential problems with Adam splitting $$20,000$ of his

superannuation contributions with Mary.
